React Functional vs Class Components

What are the main differences between functional and class components in React?

Functional components are simpler and use hooks for state and lifecycle methods, while class components use ES6 classes.

When should I use functional components over class components?

Use functional components for simpler components and when you want to leverage hooks for state management.

Are there any performance differences between the two?

Functional components can be more performant due to less overhead, especially with React's optimizations like memoization.

Can I convert a class component to a functional component?

Yes, you can convert a class component to a functional one by using hooks to manage state and lifecycle.

What are some best practices for using functional components?

Keep them pure, use hooks wisely, and avoid unnecessary re-renders by using React.memo when needed.
